TAXATION 540 INDEX 587 PRINCIPLES OF POLITICAL ECONOMY. CHAPTER I. VALUE. The first question that confronts the beginner in this science, and the one also that controls the whole scope of his inquiries to the very end, is: What is the precise subject of Political Economy? Within what exact field do its investigations lie? There is indeed a short and broad and full answer at hand to this fundamental and comprehensive question; and yet it is every way better for all concerned to reach this answer by a route somewhat delayed and circuitous, just as it is better in ascending a mountain summit for the sake of a strong and complete view to circle up leisurely on foot or on horseback, rather than to dash straight up to the top by a cog-wheel railway and take all of a sudden what might prove to be a less impressive or a more confusing view. The preliminary questions are: What sort of facts has Political Economy to deal with, to inquire into, to classify, to make a science of? Are these facts easily separable in the mind and in reality from other kinds of facts perhaps liable to be confounded with them? Are they facts of vast importance to the welfare of mankind? And are the activities of men everywhere greatly and increasingly occupied with just those things, with which this science has exclusively to do? Let us see if we cannot come little by little by a route of our own to clear and true answers for all these questions.
